ANCHOR FOR SKELETON TOWERS.

, nois, have invented new and useful Improvements' inA'ncho'rs for Skeleton Towers,'of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in anchor foot-plates for skeleton-towers and like structures.

The object of the invention is the provision of an anchor foot-plate for such structures which is of simple construction, easily secured in place, strong and durable in use, and economical of material. I accomplish these objects by shaping two plates of suitable material, preferably malleable iron or steel, to conform to a contour such that they may be securely fastened together by bolts at straight parallel portions and by a stay-plate at diverging portions thereof and when so secured provide a suitable opening between the plates for the reception of a leg of the tower and other openings to accommodate anchorrods.

The nature, characteristic features, and scope of theinvention will be more fully understood from the following description, taken in connection with the accompanying drawings, illustrating the invention, and in which like reference-numerals refer to like parts in the several views, of which Figure 1 shows in plan four foot-plates in position on the base and also shows in transverse section legs of the tower and anchorrods for the foot-plates. Fig. 2'shows a vertical section taken on 22 of Fig. 1. Fig. 3 shows a side elevation of the foot-plate. Fig. 4 shows an elevation of the foot-plate with part of a leg fastened thereon and illustrates a method of securing it by anchor-rods in the base shown in section.

As shown in the drawings, plates 1 and 2 are shaped so that, when placed together, they have coincident vertical portions 3, 4, and 5, vertical diverging portions 6, converging portions 7, slanting forward, downwardly and oppositely bulged portions 8. The plates are fastened together by rivets 9 in the vertical coincident portions 3, 4, and 5. The stayspecification of Letters Patent, v

-; plate 10, secured by rivets 11 to the diverging portions 6 of-the plates 1 and 2, is adapted to prevent their separation and to provide a confined space 12 between the diverging portions 6, through which one of the anchored rods 13 may pass. 1 Another anchor-rod 14 passes through the opening between the-bulged portion 8 of the plates.

1 and 2 coincide with the outer faces of the foot of the leg 15, which maybe an angle-iron, as shown. The leg of the tower may be fastened to the foot-plate by any suitable means, though shown as secured thereto by rivets 16.

While I have shown my foot-plate as being formed of two members, it will be understood that I do not wish to limit myself to this specific construction, as various modifications may be 1nadeas, for instance, instead of forming the plate of two members the two The inner faces of the converging portions 7 of the assembled plates side members may be formed all on a single rod or bar of material, after which the rod or material may be doubled in such manner as to bring the two side members together and form the construction shown. Various other changes may also be made without departing from the spirit of my invention, and where in the claims I have used the expression two side members it will be understood that I contemplate either two plates or the side members being formed all from one piece of material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An anchor foot-plate for steel towers and the like, comprising two plates fastened together and having diverging and converging portions, the converglng portion being shaped to have its inner face substantially coincide with that of the outer face of the foot of the leg of a tower, and anchor-rods for said foot-plate.

2. In an anchor foot-plate, in combination, plates having coincident vertical portions fastened together, a bulged-out portion providing an opening between the plates to accommodate the foot of the leg of a tower, and the like, and other bulged-out portions to accommodate anchorbolts.

3. In an anchor foot-plate, in combina tion, two plates each formed to have coincident vertical portions and other portions which first diverge from and'then converge toward the adjacent portions of the other, the said converging portions being formed to be substantially parallel with the face of the foot of the leg of a tower, 'means for fastening said plates together, and a stay-plate for said plates. 1

4. In an anchor foot-plate, in combination, two plates each formed to have coincident vertical portions and other portions which first diverge from and then converge toward the adjacent portions of the other, the said converging portions being formed to be substantially parallel with the face of the foot of the leg of a tower, means for fastening said plates together, a stay plate for said plates,.th'ere being openings between said plates to accommodate anchor-rods.

5. An anchor foot-plate having sockets formed therein for the reception of anchorrods, and a socket formed therein for the leg of the tower, .said socket bein constructed to conform to the shape ofsaid eg.

6. An anchor foot-plate for skeleton tower's comprising a pairof side members having diverging and converging portions, the converging portions being shaped to conform to the shape of the leg of the tower.

7. An anchor foot-plate comprising side members having coinciding vertical portions, a bulging-out portion providing an opening between the plates to accommodate the foot of the leg of the tower, and other bulging-out portions to accommodate anchor b'olts.

In witness whereof I have hereunto subscribed my-name; in the presence of two Witness'e's.
